description:
mk/check/check-portability: support file names with spaces

Before, file names that start or end with spaces were trimmed by read(1),
as specified by POSIX 2004 and POSIX 2018.

https://pubs.opengroup.org/onlinepubs/9699919799/utilities/read.html

This edge case bug had been present since the very beginning of this
code, in November 2006.

Filenames containing backslashes or newlines are still not supported, and
probably never will be intentionally supported.
