Changes since 5.7.24:
* There is no need to ask the dummy MAINTAINER from url2pkg whether
committing changes is ok.
* When autofixing a condition like !empty(PKGPATH:Mliteral), don't
generate unnecessary parentheses around ${PKGPATH} == literal.
* In a _VARGROUPS section, the public variables should be listed
before the private variables, to put important things first.
* When pkglint suggests to be run again with the -e, -fs or -F options,
repeat the whole command line, to allow for copy-and-paste.
* The checks for PKGPATH are fixed and enhanced. It is not a relative
path like in ../../category/package, but relative to the pkgsrc root.
* Unintended file globbing in sed commands such as s,.*,any, gets a
warning.
* MASTER_SITES should normally end with a slash, in rare cases an
equals sign or a colon are correct, too.
* Detect redundant directories in INSTALLATION_DIRS.
