Before passing the pasted text to the decoder, we now replace \r\n,
and \n, with \r.
The URI decoder was looking for a \n, which meant we failed to split
up the list and instead pasted a single “multi-line” URI.
We failed to convert the byte-indices to cell indices, resulting in a
box cursor covering the entire pre-edit string.
Note that in addition to fixing the translation from byte index to
cell index, the rendered had to be updated to dirty one extra cell
from the original grid.
Without this, we left trailing cursors behind us when the user deleted
text from the pre-edit string.
When rendering the search input box, do the same ad-hoc workaround for
combining characters with a positive x-offset as we do when rendering
normal grid cells.
In this case, we don’t *know* when we’re dealing with combining
characters. But we can detect zero-width characters. For these, check
their glyph’s x-offset. If positive, adjust it like we do when
rendering combining glyphs in the main grid, to ensure the glyph is
positioned over the _previous_ character, not the next.
When ‘selection-target’ is set to ‘none’, selecting text does not copy
the text to _any_ clipboard.
This patch also refactors the value parsing to be data driven.
The freebsd/latest image is still FreeBSD-12, with clang-8. It

ncurses on FreeBSD still uses termcap(5) while foot works fine with
xterm-256color sans status line and visible bell. Having more than
one ncurses version installed may break other applications.
Document -Dterminfo=false uses --term=xterm-256color by default
Base compiler on BSDs doesn't look where packages are installed to
avoid tainting build environment. When system fcft is installed to
the same prefix as wayland-client it passes CFLAGS that satisfy both
but when using subprojects/fcft there's a build error.

epoll/timerfd are Linux-only but BSDs have a shim via kqueue.
libwayland on FreeBSD uses epoll-shim by default, so the build may
fail at linking instead of compilation stage.

foot uses a number of functions not in any POSIX version. On non-glibc
systems defining _POSIX_C_SOURCE usually hides non-compliant interfaces.

These two buttons were encoded using the *exact* same numbers as
button 4 and 5 (scroll wheel up/down), making it impossible to
distinguish them.
The relevant section from XTerm’s control sequences documentation is:
Some wheel mice can send additional button events, e.g., by tilting the
scroll wheel left and right.
Additional buttons are encoded like the wheel mice,
o by adding 64 (for buttons 6 and 7), or
o by adding 128 (for buttons 8 through 11).
