Subject: gitk: Index line[hnd]tag arrays by id rather than row number
X-Git-Tag: v1.6.1-rc1~2^2~3
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=28593d3fa0e667bfccfe48e87a580db7c1a8d769;p=git.git

gitk: Index line[hnd]tag arrays by id rather than row number

This simplifies things a bit and is better because ids are stable
but row numbers aren't.  It also means we can avoid one [rowofcommit]
call.
