Thanks. While waiting for Bruno to say what he'd like, one more
question: in regex.h there's the documentation:
/* If this bit is set, then anchors do not match at newline
characters in the string.
If not set, then anchors do match at newlines. */
#define REG_NEWLINE (REG_ICASE << 1)
This seems to be the wrong way around; info libc says:
`REG_NEWLINE'
Treat a newline in STRING as dividing STRING into multiple lines,
so that `$' can match before the newline and `^' can match after.
Also, elsewhere in regex.h we have:
/* If true, an anchor at a newline matches. */
unsigned __REPB_PREFIX(newline_anchor) : 1;
and in the code, newline_anchor is set to true iff REG_NEWLINE is in
cflags (in regcomp):
/* If REG_NEWLINE is set, newlines are treated differently. */
if (cflags & REG_NEWLINE)
{ /* some code omitted */
preg->newline_anchor = 1;
}
else
preg->newline_anchor = 0;
So am I right in concluding that the comment for REG_NEWLINE in
regex.h is the wrong way around?
