Use bash-preexec when it is available
status: blocked by #471.
This seems like something that needs a test to catch future breaking changes. Could add a test file that checks for bash ([[ -n "$BASH_VERSION" ]]
or even [[ ! -n "$ZSH_VERSION" ]]
?), source in bash_preexec
before chruby/auto.sh
, then check if preexec_functions
was appended.
