It makes simpler the conversion from utf8 input string and makes simpler the checks done in tputc, but it still requires a lot of additional conversions that will be removed later.

tprinter() is used in tputc, so a first step is to change it to accept a wchar_t instead of a multibyte string. This patch makes more ugly the code because it needs a lot of conversions, but they will be removed later.

This parameter was always UTF_SIZ, so it is better remove it and use directly UTF_SIZ in in.

These local variables help to make expressions simpler and avoid use a pointer as induction variable in a for loop.

St runs an interactive shell and not a login shell, and it means that profile is not loaded. The default terminal configuration in some system is not the correct for st, but since profile is not loaded there is no way of getting a script configures the correct values. St doesn't update the utmp files, this is the job of another suckless tool, utmp. Utmp also opens a login shell (it is the logical behaviour when you create a new user record) it is a good option execute utmp and then get a correct input in utmp, wtmp and lastlog file, and execute the content of the profile.

When getting selected text, lines that were wrapped because of length ought not include the wrapping newline in the selection. This comes up, for example, when copying a bash command that is long enough to wrap from the console and pasting it back into the console. The extra newline breaks it. Similiarly, changes behavior when trimming whitespace from the end of a physical line to only do so if the line does not wrap. Otherwise we are trimming whitespace from the middle of a logical line, which may change its meaning. Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>

This makes any sequence of identical delimiters be considered a single word in word-snapping mode. This seems more coherent for this mode and is similar to what xterm does. Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>

This simplifies getbuttoninfo() and bpress(), and fixes a bug which made word snapping behave incorrectly when a delimiter was at the beginning or end of line. Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>
