src/leiningen/midje.clj: make-load-facts-form might use error code >125 #60
Description
In src/leiningen/midje.clj, make-load-facts-form limits the error code to 255, which is unsafe as it might clash with error codes reserved by the shell - see e.g. man 1 bash:
EXIT STATUS
The exit status of an executed command is the value returned by the
waitpid system call or equivalent function. Exit statuses fall between 0
and 255, though, as explained below, the shell may use values above 125
specially. Exit statuses from shell builtins and compound commands are
also limited to this range. Under certain circumstances, the shell will use
special values to indicate specific failure modes.
For the shell's purposes, a command which exits with a zero exit status
has succeeded. An exit status of zero indicates success. A non-zero exit
status indicates failure. When a command terminates on a fatal signal N,
bash uses the value of 128+N as the exit status.
If a command is not found, the child process created to execute it returns
a status of 127. If a command is found but is not executable, the return
status is 126.
If a command fails because of an error during expansion or redirection, the
exit status is greater than zero.
Shell builtin commands return a status of 0 (true) if successful, and
non-zero (false) if an error occurs while they execute. All builtins return
an exit status of 2 to indicate incorrect usage.
Bash itself returns the exit status of the last command executed, unless a
syntax error occurs, in which case it exits with a non-zero value. See also
the exit builtin command below.
