When git has been set to always use color in .gitconfig then I get the
warning message
Bad divisor in main::vcs_assign: 0
This is caused by vcs_file_signoffs not matching any commits due to the
pattern not understand the colour codes. Fix this by telling git log to
never use colour.

|
Notes:
|
|
Using "-f directory" may give unexpected results:
|
|
Used with "--git", git signators for _all_ files in and below
|
|
directory are examined as git recurses directories.
|
|
Any specified X: (exclude) pattern matches are _not_ ignored.
|
|
Used with "--nogit", directory is used as a pattern match,
|
|
no individual file within the directory or subdirectory
|
|
is matched.
|
|
Used with "--git-blame", does not iterate all files in directory
|
|
Using "--git-blame" is slow and may add old committers and authors
|
|
that are no longer active maintainers to the output.
|
|
Using "--roles" or "--rolestats" with git send-email --cc-cmd or any
|
|
other automated tools that expect only ["name"] <email address>
|
|
may not work because of additional output after <email address>.
|
|
Using "--rolestats" and "--git-blame" shows the #/total=% commits,
|
|
not the percentage of the entire file authored. # of commits is
|
|
not a good measure of amount of code authored. 1 major commit may
|
|
contain a thousand lines, 5 trivial commits may modify a single line.
|
|
If git is not installed, but mercurial (hg) is installed and an .hg
|
|
repository exists, the following options apply to mercurial:
|
|
--git,
|
|
--git-min-signatures, --git-max-maintainers, --git-min-percent, and
|
