Duplicated check path leads to error

[mboisson]

Hi,
I had aliased the search path with
alias reframe='reframe -C /cvmfs/soft.computecanada.ca/custom/reframe/config/settings.py -c /cvmfs/soft.computecanada.ca/custom/reframe/checks'

Then, I wanted to use just a subdirectory, so I used :
reframe -R -r -c /cvmfs/soft.computecanada.ca/custom/reframe/checks/advanced/osu

but it failed because it found a duplicate test (i.e. the same one) :

Command line: /home/mboisson/.local/easybuild/software/2017/Core/reframe/2.21/bin/reframe -C /cvmfs/soft.computecanada.ca/custom/reframe/config/settings.py -c /cvmfs/soft.computecanada.ca/custom/reframe/checks -R -r -c /cvmfs/soft.computecanada.ca/custom/reframe/checks/advanced/osu

When there are multiple -c argument, it would be more intuitive to overwrite the previous value, rather than concatenate them ?

Hi @mboisson, this is my bad when I suggested that before. I am quoting from the documentation:

However, you can build your own check path by specifying multiple times the -c option.

-c appends to the path. I agree perhaps we should make it accept paths in the form path1:path2 etc. and if specified multiple times the latter override the previous ones.
