Subject: gitweb.js: fix null object exception in initials calculation
X-Git-Tag: v1.6.6-rc1~7^2~4
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=e42a05f75c9ff5d10d0b8f6784fc244873818a99;p=git.git

gitweb.js: fix null object exception in initials calculation

Currently handleLine() assumes that a commit author name will always
start with a capital letter. It's possible that the author name is
user@example.com and therefore calling a match() on the name will fail
to return any matches. Subsequently joining these matches will cause an
exception. Fix by checking that we have a match before trying to join
the results into a set of initials for the author.
