![Andrei Rybak](/assets/img/avatar_default.png)
Fix typos in code comments which repeat various words. Most of the cases are simple in that they repeat a word that usually cannot be repeated in a grammatically correct sentence. Just remove the incorrectly duplicated word in these cases and rewrap text, if needed. A tricky case is usage of "that that", which is sometimes grammatically correct. However, an instance of this in "t7527-builtin-fsmonitor.sh" doesn't need two words "that", because there is only one daemon being discussed, so replace the second "that" with "the". Reword code comment "entries exist on on-disk index" in function update_one in file cache-tree.c, by replacing incorrect preposition "on" with "in".

# Uses a methodology similar to
|
|
# t6042: corner cases with renames but not criss-cross merges
|
|
# t6036: corner cases with both renames and criss-cross merges
|
|
# t6423: directory rename detection
|
|
#
|
|
# The setup for all of them, pictorially, is:
|
|
#
|
|
# A
|
|
# o
|
|
# / \
|
|
# O o ?
|
|
# \ /
|
|
# o
|
|
# B
|
|
#
|
|
# To help make it easier to follow the flow of tests, they have been
|
|
# divided into sections and each test will start with a quick explanation
|
|
# of what commits O, A, and B contain.
|
|
#
|
|
# Notation:
|
|
# z/{b,c} means files z/b and z/c both exist
|
|
# x/d_1 means file x/d exists with content d1. (Purpose of the
|
|
# underscore notation is to differentiate different
|
|
# files that might be renamed into each other's paths.)
