* Fix non-portable doc comments warning
A line starting with > might be interpreted as a block quote.
In regular markdown this could be prevented by escaping the `>`
using a backslash. However, since the doc comments are used by
clap for the long help more or less verbatim, the `\` would be visible
hence the shuffling around of words.
* Use `.contains()`
When core.quotepath is true (the default) then non-ASCII chars
in a file name are quoted. These quotes hide the DIFF_PREFIXES and
"a/1" "b/1" remains as such, instead of becoming "1" "1".
This was interpreted by delta as renamed file. Now these quotes are
removed before the DIFF_PREFIXES are searched.
`diff -u file1 file2` output starts with '--- file1', a '-- 12' line
being removed results in '--- 12', which was interpreted as the start of
a new diff. Now the number of removed lines announced in the header as e.g.
'@@ -1,4 +1,3 @@' is taken into account for this specific diff input.
Upgrade "time" (and its dependency chain rooted at "plist"), the previous
version did not build with 1.80.
Tell the new 'unexpected_cfgs' lint that 'tarpaulin_include' is okay
Mark one clippy lint as a false positive
Tell clap to not wrap output, append `after_long_help()` (with matching
ansi codes in this section), then manually wrap the result.
The help output is now paginated if writing to a terminal.
All code paths flow back to main(), so an invoked pager is properly
waited for (by the OutputType drop impl).
Use new, smaller PagerCfg instead of the full Config, as for
pager output only 3 variables are relevant.
oneshot_write() can be used to write paginated output, usually
before exiting.
--max-line-length increased to 3000, highlighting now stops after 400
characters. In that case the highlighting may be incorrect until it
is reset for the next hunk.
Document that the input of `truncate_str()` may be cut on a double width
char ("fullwidth") - then the output is no longer a prefix of the input.
`truncate_str_short()` could be faster by not constructing the result and
instead only returning an index, but it will be used in rare edge cases so
reusing existing logic is good enough.
Common code moved to `truncate_str_impl()`.
Assume (with fallback) that graphemes are at most 2 wide.
Fewer allocations.
Tests.
