Hi,
Attached is my fourth--and what I anticipate to be the final--re-roll of
my series to add teach 'git-grep(1)' a new '--column' flag.
Since last time, I have changed the following:
* Respond to Ævar's review suggesting that I (1) change git-jump's
README, (2) use --column over --column-number, and (3) use /*\n, not
/**\n. [1].
This change comprises the majority of the inter-diff between v3..v4,
which is added below for conveniency. I have chosen to additionally
rename the configuration variables from columnNumber to column, to be
consistent with the new flag name.
Thanks in advance for your review. I am going to send out my next patch
(which Ævar suggested) to add '--only-matching' to 'git-grep(1)'.
Thanks,
Taylor
