PR225692: localedef: mark "space" also as "print" excluding known conflicts

[yuripv]

Summary

PR: 225692

The POSIX locale definition says the following:

print

Define characters to be classified as printable characters, including the <space>.

In the POSIX locale, all characters in class graph shall be included; no characters in class cntrl shall be included.

In a locale definition file, characters specified for the keywords upper, lower, alpha, digit, xdigit, punct, graph, and the <space> are automatically included in this class. No character specified for the keyword cntrl shall be specified.

---

So it doesn't explicitly say anything about "space" here, though it doesn't NOT explicitly forbid including "space" in the "print" class, and I *think* we can extend the <space> character being included to the entire "space" character class.

Test Plan

Build/install in share/ctypedefs, run the test case attached to PR225692.

LGTM.
(I currently don't have the time to go over to Release Engineering for this though ::-/ )

No objection from me, although I am not very familiar with this particular code or POSIX in this area.

Ditto pfg—I don't have time to do re's process to commit this to head while it is frozen.

rebase on top of recent localedef changes; make the change less intrusive keeping the warning and only stripping "print" from "space|control" combination.
