Commit Message

Alan Modra April 3, 2019, 2:28 a.m.
Underscore was specified twice in all these patterns, and backslash
twice in some.  Flex warned about the $SYSROOT rule, which is covered
by earlier rules:  "ldlex.l:386: warning, rule cannot be matched".

	* ldlex.l: Formatting.
	(CMDFILENAMECHAR, CMDFILENAMECHAR1): Delete.
	(FILENAMECHAR1, SYMBOLNAMECHAR1, SYMBOLCHARN, FILENAMECHAR),
	(WILDCHAR, NOCFILENAMECHAR): Remove duplicate chars.  Reorder.
	(<INPUTLIST>"$SYSROOT"..): Delete rule.
