    Handle execvp() failures. · 746cbc63
    Alexandre Duret-Lutz authored 
    When running `Display' in TAF-Kit's editor would enter a warp zone
if dotty is not in PATH: because of the missing exit() after
execvp(), two forks of TAF-Kit's editor would compete for the
terminal.

* include/vaucanson/tools/out_display.hxx (out_display): Exit
if execvp returns an error, and report the failure.
