git-pickaxe: allow "-L <something>,+N"
With this,
git pickaxe -L '/--progress/,+20' v1.4.0 -- pack-objects.c
gives you 20 lines starting from the first occurrence of
'--progress' in pack-objects, digging from v1.4.0 version.
You can also say
git pickaxe -L '/--progress/,-5' v1.4.0 -- pack-objects.c
