[nongnu] elpa/bash-completion 1d41c58bd5 192/313: Send initialization command as one string, as long as possible.

[ELPA Syncer]

branch: elpa/bash-completion
commit 1d41c58bd5d5a143884ac52d826c0bdd3ae89ebe
Author: Stephane Zermatten <szermatt@gmx.net>
Commit: Stephane Zermatten <szermatt@gmx.net>

    Send initialization command as one string, as long as possible.
    
    With this commit, bash-completion-require-process avoids using
    bash-completion-send, and so wait for process output, until process
    output is actually useful. This might make a difference on slow remote
    connections.
