Thanks!

I think it is better to say "Usage: set substitute-path FROM TO".

GNU standards dislike such usage of the word ``path''. We should use
``file name'' instead. (``Path'' is reserved for lists of directories,
such the values of $PATH and $MANPATH environment variables.)

I suggest to say this instead:

Delete the rule for substituting FROM in source file names. If FROM
is not specified, all substituting rules are deleted.
If the debugger cannot find a rule for FROM, it will display a
warning.

Same here.
