[PATCH v4 0/7] replacing strbuf_getline_lf() by strbuf_getline()

[Moritz Neeb <lists@moritzneeb.de>]

Although I was not sure [4], I decided to roll out v4, in the hope that the next
reviewers will profit by the more polished commit messages and order.

This series deals with strbuf_getline_lf() in certain codepaths:
Those, where the input that is read, is/was trimmed before doing anything that
could possibly expect a CR character. Those places can be assumed to be "text"
input, where a CR never would be a meaningful control character.

The purpose of this series is to document these places to have this property,
by using strbuf_getline() instead of strbuf_getline_lf(). Also in some codepaths,
the CR could be a leftover of an editor and is thus removed.

Every codepath was examined, if after the change it is still necessary to have
trimming or if the additional CRLF-removal suffices.

The series is an idea out of [1], where Junio proposed to replace the calls
to strbuf_getline_lf() because it 'would [be] a good way to document them as
dealing with "text"'. 

Changes since v3 [3] (the changes to single patches are indicated below):

 * Commit messages refined
 * Order of patch 4 and 5 in v2 was switched.

The interdiff only removes an empty line (I noticed, when changing the order of
commits, that the splitting operation had no newline before this whole series,
so I left it that way):
