[PATCH] quotearg: minimize shell quoting using double quotes |
|
Date: |
Mon, 26 Sep 2016 15:22:45 +0100 |
* lib/quotearg.c (quotearg_buffer_restyled): If an ASCII single
quote in encountered then use double quotes (c style quoting)
when it simplifies the quoting.
* tests/test-quotearg-simple.c: Add test cases.
* tests/test-quotearg.h (use_quotearg_buffer): Adjust to account
for the fact we now may write beyond the returned length.
