Strange: one can't write a collection with range [X-Y] where Y is the
character ']'.
I thought the following should work, but it doesn't:
/[@-\]]
Problem: the range is '@' to '\', and ']' ends the collection; the next ']'
matches itself.
(It's surprising that '\]' within '[]' not always means ']' literally!)
Ok, so the char directly after '-' ends the range?
/[@-]]
No, the collection is '[@-]' followed by ']' which matches itself. The
help says it:
| For '-' you can also make it the first or last character: "[-xyz]",
| "[^-xyz]" or "[xyz-]".
Ok, this works:
/[@-\\]]
but it matches the range '@-\' plus the char ']'.
A range where \] is the first character works:
/[w\]-a]\C
matches ] ^ _ ` a w
Is it a bug that '\' after '-' in a collection is taken literally?
