Paul Smith bf7f690202 Directly handle $\ line endings ... Previously we used the fact that this line ending expanded to "$ " which would then expand to the empty string. This has problems if you enable warnings for undefined variables, so directly implement this special (but documented) trick in the GNU Make parser. As a side-effect this also removes all previous whitespace when in GNU Make mode (not in POSIX mode) just as it would without "$". * src/misc.c (collapse_continuations): Check for "$\" and remove it. * tests/scripts/variables/flavors: Add regression tests including with previous whitespace, and escaped/unescaped "$"		2023-02-26 17:30:15 -05:00
