Package: bzr
Version: 2.3.0-2
Severity: normal
I have a few aliases to run bzr diff with an external diff engine, in
particular "diff -bu" and "wdiff -n". I don't know exactly when, since
I don't use them often, but they stopped working in the recent past (a
few months maybe) when the invocation of the external tool uses
parameters. bzr tries to run a program called "wdiff -n", rather than
invoke "wdiff" with the "-n" parameter, as evidenced by the following
strace:
