27 # the `want_color()` function special-cases the situation where a pager was
28 # spawned and Git now wants to output colored text: to detect that situation,
29 # the environment variable `GIT_PAGER_IN_USE` is set. However, color is
30 # suppressed despite that environment variable if the `TERM` variable
31 # indicates a dumb terminal, so we set that variable, too.
34 # The first element of $@ may be a shell function, as a result POSIX
35 # does not guarantee that "one-shot assignment" will not persist after
36 # the function call. Thus, we prevent these variables from escaping
37 # this function's context with this subshell.
