okay, that one ought to work.

revert Subst.pm r1.24 again, it breaks package creation

'+' is a widely used character in LIBxxx_VERSION, e.g. LIBFLAC++_VERSION.
Making it illegal breaks numerous packages.

sorry, somehow I did redo this line badly and didn't retest

Revert Subst.pm r1.22. It broke ordinary pkg_add usage

add some limited capability to -DVAR+=value
to be used with REGRESSION_TESTING, where it's somewhat inconvenient to
know the full list in advance.

tweak fragment handling error messages a bit
don't pass parameters we don't need

move to use v5.36;
tested by me over the last few weeks, and tb@
also fixed a "manual install" bug properly reported by tb@

aside that there should be *no functional change*.
If you see any message

If you see any message like "hey, the number of params is wrong"
it is a fringe case I didn't run into and should be easy to fix.

more descriptive comment

add the strerror to the error message

pass file name thru to Subst for better error messages.

remove $_ usage that warns under perl 5.18

The pkg_subst / SUBST_CMD has caused issues for some ports where
the $\ in files was replaced by $. Now only removes the \
in $\{[A-Za-z_]

Ok espie@

handle failures from ports tree with more care.
this does avoid infinite loops in case of wrong plists.
necessary since print-plist-with-depends CAN fail...

initial scaffolding for @rcscript: for now, acts like normal files,
but allow absolute pathnames (treat that as an implicit @cwd).

allow say and errsay to work without parameters, as it's ways common.
create verbose_system up in state, because it makes sense without verbose.

whitespace cleanup

have subst return a handle to written file

whitespace fixes

bad espie: use strict/warnings consistently, and fix two nits and two
actual errors !

Say goodbye to local $_
lexical scoping is so much neater (courtesy of perl 5.10)

allow direct copy of fh to another

typo, fix fragments

tweak a bit, allow ^ to occur at beginning of variable name

likewise for the hash itself

I should know better... reuse methods internally as much as I can, to
facilitate further changes.
