[parted-devel] [PATCH] ui: do not initialize readline (which would output!) in --script mode

[Jim Meyering]

I noticed some unexpected control characters at the beginning of actual
output from parted, and tracked it down to a bug whereby rl_initialize
was being called in spite of my use of --script (-s).

Note that this effect disappears if you set e.g., TERM=dumb
or unset TERM, as is done in the tests/test-lib.sh, but if you
set e.g., TERM=xterm, it would print the control characters.
