In the info page for "chmod invocation",
node 27.2 Symbolic Modes, <quote>

The format of symbolic modes is:

[ugoa...][+-=]PERMS...[,...]

</quote>
the [+-=] is naturally read as "every character from + through =" due
to the special meaning of - in a character class.  I suggest [+=-]
would be more apt.  It is possible the same pattern is repeated
elsewhere in the manual.

[-+=] was already used in chmod --help so I went with that.
I'll push the attached in your name in a while.

thanks,
