Description:

Currently, makepkg performs unnecessary tasks which are nowhere documented (e.g. wiki, manpage, ...): If the PKGBUILD contains the variables _svntrunk and _svnmod it looks for the latest svn revision of the code and REPLACES pkgver with what it gets.

This is wrong IMO for at least two reasons:
1. It is useful to be able to extract a svn tree at a specific revision number, regardless of further upstream updates (which may break things more than fix them). always fetching the last update is wrong. Having makepkg force and not respect the intention of the package builder is wrong.
2. It is my understanding that user variables in PKGBUILDS are prefixed by "_". So should be considered both _svntrunk and _svnmod. If makepkg makes an explicit usage of them, it should use other names.

So my feature request is simply to remove this "functionality" from makepkg. To stick with the KISS mantra, the user should determine by himself the last revision number if he wishes so. And makepkg should not interfere otherwise.
