[Xen-devel] [OSSTEST PATCH 17/27] mg-show-flight-runvars: Decorate synth runvar names with ~

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

Make mg-show-flight-runvars -a append ~ to the names of synth runvars.
(This is consistent with the new syntax in cs-job-create.)

We do this by editing $row->[1] (and $colws[1]) so we can avoid
disturbing the general column format calcuation and printing; this
means we have to copy $row (because the value in the DB $row is
readonly).

We have to check for $synth eq 'f' as well as $synth being boolean
false, because SQLite's typeless nature (or, to put it another way,
DBD::SQLite's failure to look at the schema) means that a boolean
field's value of 'f' or 't' is simply returned as a string to Perl.
But of course "f" is trueish in Perl.
