Quoted strings cannot start within another quoted string and end after
that other string has ended. Therefore single-quoted and double-quoted
strings should (as much as possible) be colorized by a single rule, so
that overlapping colorations are avoided.
(This also fixes a double typo in the PHP syntax (\. --> \\.) that has
been there since the PHP syntax was added in 2008, commit 90ee8ee4.)
This fixes https://savannah.gnu.org/bugs/?61387.
Bug existed since each of these syntaxes was introduced,
the oldest ones around 2006, a few others around 2015.
The one that got it right was the Lua syntax from 2011.
Within a bracket expression, the backslash is not special,
so it does not need to be escaped.
The double backslashes within brackets were found with:
grep -o '\[[^][]*\\\\[^][]*\]' syntax{,/extra}/*rc
Also, incorporate the square brackets into some bracket expressions
by listing the closing bracket first, saving a separate regex for
those two brackets.
Removals:
- All eblits were dropped from Gentoo years ago.
- HDEPEND was never fully approved, superseded by BDEPEND.
- Keywords 'dohard' and 'dosed' have been banned since EAPI 4:
https://projects.gentoo.org/pms/5/pms.html#x1-130001r8
- Several arches are dead. For the currently supported list:
https://gitweb.gentoo.org/repo/gentoo.git/tree/profiles/arch.list
Additions:
- Two eapply functions replace the epatch functions, but epatch
is still supported until EAPI 6 is banned.
- Modern build systems (ninja and qmake5) have new functions.
- EAPI 7 added more builtins: dostrip, get_libdir, ver_*
- Highlight the cross-compiler boolean function. (There are too
many toolchain functions to add them all, but this one is very
common and has a long name, so highlighting it is useful for
catching typos early.)

Add IDEPEND from EAPI 8, and also add more EAPI 7 roots so that all
of ROOT, EROOT, SYSROOT, ESYSROOT, and BROOT are supported.
