Remove the limitation on the number of dead keys
that we match, and allow the result be be multiple
characters.
Regenerate the builtin sequences, since this changes
what dead key sequences we can reproduce algorithmically.
Update tests to match.
Fixes: #10
Apply heuristics to avoid breaking users existing configurations
with the change to not always add the default sequences.
If we find a cache that was generated before 4.4, and the Compose
file does not have an include, and doesn't contain so many sequences
that it is probably a copy of the system one, we take steps to keep
things working, and thell the user about it.
All tables use the compact format now, and we generate
caches in that format too. Bump the cache version to 3
for this.
Replace the python script for generating the builtin table
by a small C program using the same code to generate the data
for the builtin table. This drops the restriction on only
generating a single character in the builtin sequences.
This was breaking muscle memory of people with
the us intl keyboard layout, for important keys
such as '. The unfortunate side-effect is that
our handling of <dead_acute> is a bit hampered
by sequences that don't fit the pattern. But
such is life.
Fixes: #3807
Update our compose sequences based on the current
update xorg Compose.pre file. Beyond that, remove
some deadkey sequences that we are now handling
(better) in code.
