Fork

Yet another shell (yash), version 2.15.

This version includes many bug fixes.

Yash 2.15

+ An interactive shell now can be interrupted by SIGINT.
+ Bracket expressions in pathname expansion are now fully supported (provided that libc's regex implementation is correct).
= The "suspend" builtin now requires the -f option to suspend an interactive shell that is a session leader.
= The shell no longer automatically sets the $YASH_LE_TIMEOUT variable.
= A job-control shell now stops itself when invoked in the background.
= A job-control shell no longer ignores SIGTTOU by default.
= The '--nocaseglob' option no longer affects pattern matching in parameter expansions of form "${var#xxx}" etc.
* Fixed pathname expansion on redirection target.
* Couldn't set a signal handler to the default by the "trap" builtin if the signal was ignored on invocation of an interactive shell.
* Fixed accidental interruption of builtins by signals.
* Fixed parser so that a non-simple command is properly parsed after alias substitution.
* Various bug fixes
