Relax initial regexp to match more instances, but add a
filter to avoid some invalid conversions. Run this:
git grep -l "\`[^']*'" tests | xargs perl -pi -e '$q=q"'\''";' \
-e '$q="$q\\$q$q"; /(= ?\`|\`expr|\`echo|\Q$q\E)/ and next;' \
-e ' s/\`([^'\''"]*?'\'')/'\''$1/g'
The last disjunct in the above (...) filter is to exempt
any line that contains this string: '\''
With quoting like that, converting a ` to ' is likely to cause trouble,
so we'll handle those manually. Here are three examples where
the exemption is required:
*': `link-to-dir/'\'': hard link not allowed for directory'*) ;;
printf 'creating file `%s'\''\n' $f
'mv: inter-device move failed: `%s'\'' to `%s'\'';'\
Automatically adjust both the source (now in only one place)
and all tests that expect the resulting output via this:
git grep -l 'Try.*--help' src/system.h tests \
| xargs perl -pi -e 's/Try \\?`(\S+ --help)/Try '\''$1/'

* doc/coreutils.texi (checkOrderOption) New macro for
describing `--check-order' and `--nocheck-order', used in
both join and comm.

(usage): Describe new options.
(compare_files): Keep an extra pair of buffers for the previous
line from each file to check the internal order.
(check_order): If an order-check is required, compare and handle
the result appropriately.
(copylinebuffer): Copy a linebuffer; used for copy before read.
* tests/misc/Makefile.am: List new test.
* tests/misc/comm: Tests for the comm program, including the
