[GRASS-dev] i.pca doesn't have the '--o' flag

[Nikos Alexandris]

Vaclav,

indirectly relevant with the standard flags discussion which is related to the 
"prefix"es is the following:

I likely have zero idea about "why prefix-es and not suffix-es". And I might 
just add noise but I mostly prefer adding a suffix.  I think this keeps things 
cleaner and makes it easier to search for maps when there are too many. They 
are just, when alphabetiaclly ordered, close to each other :-).

So, why do grass modules prefer prefix-es? Why not suffix-es? Why not, at 
least, give the user the freedom to select upon?  Isn't this related with the 
whole discussion?

Ευχαριστώ, Nίκος
