Permit Windows ends-of-line in allcrcs-abbrev.txt verification.

madler · madler · commit 7a443bb83d99 · 2020-12-30T14:44:03.000-08:00
Windows inserts a non-standard carriage return before the line
feed when writing text files. This allows the check to succeed if
one file has carriage returns and the other does not. This also
permits variations in the amount and kind of white space.
