diff: fix side-by-side output with tabbed input

2022-12-14T01:31:21+00:00

The previous logic conflated some things... in this block:
- j: input characters rendered so far
- nc: number of characters in the line
- col: columns rendered so far
- hw: column width ((h)ard (w)idth?)

Comparing j to hw or col to nc are naturally wrong, as col and hw are
limits on their respective counters and nc is already brought down to hw
if the input line should be truncated to start with.

Right now, we end up easily truncating lines with tabs in them as we
count each tab for $tabwidth lines in the input line, but we really
should only be accounting for them in the column count.  The problem is
most easily demonstrated by the two input files added for the tests,
the two tabbed lines lose at least a word or two even though there's
plenty of space left in the row for each side.

diff: tests: loosen up requirements for report_identical

2022-04-19T04:04:13+00:00

This test cannot run without an unprivileged_user being specified
anyways, so just run as the unprivileged user.  Revoking read permisions
works just as well if you're guaranteed non-root.

diff: fix failed compare when ignoring file case

2022-02-18T15:51:38+00:00

With --ignore-file-name-case we need to compare files regardless of
case. We need to propigate both names down to diffit so we can look up
the correct file when the names differ based on case, otherwise we try
to look up the file using the case from the a tree which might not be
discoverable if its case is different in the b tree.

When diffing files and directories, don't follow symbolic links, instead
compare where the links point to.

diff: Detect Objective-C methods

2022-02-18T15:09:57+00:00

When searching back for function definitions, consider lines starting
with '+' and '-', this allows us to pick up Objective-C methods as well
as C style function definitions.
