Bash-4.2 patch 14

[thirdparty/bash.git] / tests / tilde.tests

# this is needed because posix mode restricts tilde expansion to assignment
# statements preceding a command, instead of the default of expanding all
# assignment statements on the line (e.g., after `export').  Without this,
# the next-to-last test fails
