Thanks I tried the following

quim-hojas-problemas = quim-hojas-problemas
curso_2016_17 = curso_2016_17
[subpaths]
https://bitbucket.org/kalthad/hgquim-num-estad/curso_2016_17  = https://bitbucket.org/kalthad/curso_2016_17
https://bitbucket.org/kalthad/hgquim-num-estad/quim-hojas-problemas =
https://bitbucket.org/kalthad/quim-hojas-problemas

When I pushed to bitbucket I obtained

pushing subrepo curso_2016_17 to https://kalthad@bitbucket.org/kalthad/hgquim-num-estad/curso_2016_17

What do I miss?
