xbps-uhelper: add verbose output for cmpver/pkgmatch

[classabbyamp]

I can never remember which retval means which thing. This only prints if -v/--verbose is specified.

Examples:

$ ./bin/xbps-uhelper/xbps-uhelper -v cmpver 1 2 ; echo ret: $?
1 < 2
ret: 255
$ ./bin/xbps-uhelper/xbps-uhelper -v cmpver 1 1 ; echo ret: $?
1 = 1
ret: 0
$ ./bin/xbps-uhelper/xbps-uhelper -v cmpver 2 1 ; echo ret: $?
2 > 1
ret: 1
$ ./bin/xbps-uhelper/xbps-uhelper -v pkgmatch 'foo-1.0_1' 'foo>=0' ; echo ret: $?
foo-1.0_1 matches foo>=0
ret: 1
$ ./bin/xbps-uhelper/xbps-uhelper -v pkgmatch 'foo-1.0_1' 'foo<0.1_1' ; echo ret: $?
foo-1.0_1 does not match foo<0.1_1
ret: 0

it also seems that getting an error from pkgmatch is currently impossible

Nice, can you add completion too?

I've fixed that CI failure in f117b1f

What about printing this to stderr instead of stdout?

[classabbyamp]

yes good idea
