it has been reported that duriing reading pkgbuilds with latin-1 charset
the execption will be raised. Well, it is one more point to rewrite
parser to use own impl instead of shlex and parse raw byte array instead
It has been found that there are two cases in which pkgbuild was not
parsed correctly
1. Major case in which there is quotation mark inside comment line,
which would cause ValueError: No closing quotation error
2. Minor case, if there are utf symbols in pkgbuild file (e.g.
hieroglyphs, see ttf-google-fonts-git), it will case incorrect
reading in `_is_escaped` method
The issue appears in case if versions ar the same (e.g. rebuild); in
this case printer doesn't increment version as builder does.
Also util has been renamed to utils, keeping backward compatibiltiy
