editor use the value of this
	variable when it is set, and the environment variable
	`GIT_EDITOR` is not set.  See linkgit:git-var[1].

core.commentChar::
core.commentString::
	Commands such as `commit` and `tag` that let you edit
	messages consider a line that begins with this character
	commented, and removes them after the editor returns
	(default '#').
+
If set to "auto", `git-commit` would select a character that is not
the beginning character of any line in existing commit messages.
+
Note that these two variables are aliases of each other, and in modern
versions of Git you are free to use a string (e.g., `//` or `⁑⁕⁑`) with
`commentChar`. Versions of Git prior to v2.45.0 will ignore
`commentString` but will reject a value of `commentChar` that consists
of more than a single ASCII byte. If you plan to use your config with
older and newer versions of Git, you may want to specify both:
+
    [core]
    # single character for older versions
    commentChar = "#"
    # string for newer versions (which will override commentChar
    # because it comes later in the file)
    commentString = "//"

core.filesRefLockTimeout::
	The length of time, in milliseconds, to retry when trying to
	lock an individual reference. Value 0 means not to retry at
	all; -1 means to try indefinitely. Default is 100 (i.e.,
	retry for 100ms).

core.packedRefsTimeout::
	The length of time, in milliseconds, to retry when trying to
	lock the `packed-refs` file. Value 0 means not to retry at
	all; -1 means to try indefinitely. Default is 1000 (i.e.,
	retry for 1 second).

core.pager::
	Text viewer for use by Git commands (e.g., 'less').  The value
	is meant to be interpreted by the shell.  The order of preference
	is the `$GIT_PAGER` environment variable, then `core.pager`
	configuration, then `$PAGER`, and then the default chosen at
	compile time (usually 'less').
+
When the `LESS` environment variable is unset, Git sets it to `FRX`
(if `LESS` environment variable is set, Git does not change it at
all).  If you want to selectively override Git's default setting
for `LESS`, you can set `core.pager` to e.g. `less -S`.  This will
be passed to the shell by Git, which will translate the final
command to `LESS=FRX less -S`. The environment does not set the
`S` option but the command line does, instructing less to truncate
long lines. Similarly, setting `core.pager` to `less -+F` will
deactivate the `F` option specified by the environment from the
command-line, deactivating the "quit if one screen" behavior of
`less`.  One can specifically activate some flags for particular
commands: for example, setting `pager.blame` to `less -S` enables
line truncation only for `git blame`.
+
Likewise, when the `LV` environment variable is unset, Git sets it
to `-c`.  You can override this setting by exporting `LV` with
another value or setting `core.pager` to `lv +c`.

core.whitespace::
	A comma separated list of common whitespace problems to
	notice.  'git diff' will use `color.diff.whitespace` to
	highlight them, and 'git apply --whitespace=error' will
	consider them as errors.  You can prefix `-` to disable
	any of them (e.g. `-trailing-space`):
+
* `blank-at-eol` treats trailing whitespaces at the end of the line
  as an error (enabled by default).
* `space-before-tab` treats a space character that appears immediately
  before a tab character in the initial indent part of the line as an
  error (enabled by default).
* `indent-with-non-tab` treats a line that is indented with space
  characters instead of the equivalent tabs as an error (not enabled by
  default).
* `tab-in-indent` treats a tab character in the initial indent part of
  the line as an error (not enabled by default).
* `blank-at-eof` treats blank lines added at the end of file as an error
  (enabled by default).
* `trailing-space` is a short-hand to cover both `blank-at-eol` and
  `blank-at-eof`.
* `cr-at-eol` treats a carriage-return at the end of line as
  part of the line terminator, i.e. with it, `trailing-space`
