Window and tab titles are changed by emitting an unprintable escape
sequence to the terminal. These escape sequences do not play nicely
with the TAB character on multiple terminal emulators--they create
un-deletable characters on the first line after command execution.
Sending "\r" after changing the window and tab titles allows all
characters on the first line to be deleted.
Fixes#11314
The `title` function unsafely prints its input without sanitization, which if used
with custom user code that calls it, it could trigger command injection.
The `spectrum_ls` and `spectrum_bls` could similarly be exploited if a variable is
changed in the user's shell environment with a carefully crafted value. This is
highly unlikely to occur (and if possible, other methods would be used instead),
but with this change the exploit of these two functions is now impossible.
In Ubuntu and Debian, in scp, and in rsync the prompt is by default specified as in
user@hostname:/path/to/directory
while the previous title in ohmyzsh was
user@hostname: /path/to/directory
DISABLE_UNTRACKED_FILES_DIRTY, DISABLE_AUTO_TITLE, GIT_STATUS_IGNORE_SUBMODULES are not set
Handle these variables not being set with conditional access.
If the user has set -u option to report attempts to use undeclared / unassigned variable, accessing the variables needs to be conditional.
* Automatic title: Replace fg with description from jobs
* Avoid error messages when there is no job
* Use $jobstates and $jobtexts to look for jobs
`jobs %string` doesn't work correctly when run inside `$()`. `$jobstates` and
`$jobtexts` is available in the current shell process, so even though we need
to replicate a bit more logic, every type of `fg` invocation works correctly.
* lib: clean up termsupport.zsh

Apple's Terminal doesn't open a new tab in your current directory if your hostname has UTF-8 characters in it. Percent encoding the host in addition to the path in update_terminalapp_cwd appears to solve this issue.

Use add-zsh-hook to add functions to hooks. That way they won't be added again
when doing `source ~/.zshrc` multiple times.

Currently, the title is only set on supported terminals (i.e. xterm,
urxvt, screen etc.). Using terminfo entries to set the terminal title
adds support for many more terminals.
