Not quite. The ereg_* functions are based on POSIX 1003.2, which states:
"A bracket expression is a list of characters enclosed in `[]'.
<snip> If two characters in the list are separated by ` -', this is
shorthand for the full range of characters between those two (inclusive) in
the collating sequence... <snip> To include a literal `-', make it the
first __or last character__, _or the second end-point of a range_. <snip>"
