             Bug #: 15012
           Summary: online docs for "alias" command are unclear
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
        AssignedTo: unassigned@sourceware.org
        ReportedBy: dje@google.com
    Classification: Unclassified


The help docs for the "alias" command say this:

Usage: alias [-a] [--] ALIAS = COMMAND
ALIAS is the name of the alias command to create.
COMMAND is the command being aliased to.

A user could infer that COMMAND means command + arguments.

E.g.

alias nosegv = handle SIGSEGV nostop noprint pass
alias segv = handle SIGSEGV stop

This doesn't work, but the user could think it should.

Same reasoning probably applies to the texinfo docs.

Rather than fixing the docs, maybe "alias" could be fixed
to make this work.  It seems possibly handy.

That was left for another day!!!
[the relative effort being sufficiently different]
But if someone wants to take it on ...

This works since this commit:
