[Octave-bug-tracker] [bug #60413] build: sed expression problems when prefix is empty or slash

[Rik]

Follow-up Comment #21, bug #60413 (project octave):

I don't think it's super critical, but we've used the explicit form of
variable substitution in other parts of Octave.  For example, if you look in
doc/interpreter/module.mk you will find


        $(PERL) $(srcdir)/%reldir%/munge-texi.pl $(top_srcdir) 
$(DOCSTRING_FILES) <
$< > $@-t && \


This could have been written "$PERL", but the extra parentheses really make it
clear that we are doing variable substitution.

In this case, we could write "$(SED)", but "$SED" is probably fine too.
