This series will teach git grep to match at specified line numbers. This is
particular usefull, if you want to see the lines which emits warnings or errors
from a build run (where you only get the line number) and present it nicely to
the user with function and context lines.
The implementation is split-up into preperation patches which are only noise:
Bert Wesarg (4):
grep: prepare for re-using the space of the regexp member in struct
grep_pat
This one moves the regexp member into an union, so that we can later re-use
the space for the line number information.
grep: pass current line number down to match_one_pattern
To actually match at the line number, the function match_one_pattern needs
to know the current line number, do it with this patch.
grep: introduce pattern which matches at line number
This implements the line number matching in the low level grep machinery.
grep: provide option to match line number
And lastly, this exposes the new feature by a new -@ option to git grep.
Patch 5 will than support comma separated line ranges as argument to -@, but
this work has not yet started.
