Subject: [PATCH] gitk: Allow specifying tabstop as other than default 8 characters.
X-Git-Tag: v1.5.3-rc0~49^2~19
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=7e12f1a6291032a311ab592e42fd38f5ec358c0e;p=git.git

[PATCH] gitk: Allow specifying tabstop as other than default 8 characters.

Not all projects use the convention that one tabstop = 8 characters, and
a common convention is to use one tabstop = one level of indent.  For such
projects, using 8 characters per tabstop often shows too much whitespace
per indent.  This allows the user to configure the number of characters
to use per tabstop.
