Setting main-options to --follow doesn't work well with commit graph

[CervEdin]

The problem

The log --follow option doesn't play nice with the commit graph in Tig.

Examples

For example, in the tig repository, if you run

tig Makefile

and have the following two options set

set main-options = --follow
set main-view = commit-title:yes,graph=v2

then each sequence of continuous commit will show up as if it occurred on different branches

Another example, same options but runing tig book.md

6Y JFonseca ∙ Add testing docs to GitBook and add ignore file
6Y JFonseca │ ∙ Move screenshot link to the end of the table of contents
6Y JFonseca │ ∙ Link directly to screenshot album on flickr
6Y JFonseca │ │ ∙ Use Gitbook for generating the GitHub site files

and the corresponding git log --oneline --graph --follow book.md

...
* cef17fc Move screenshot link to the end of the table of contents
* ac6e3e3 Link directly to screenshot album on flickr
...
* 248592b Use Gitbook for generating the GitHub site files

This is not a problem if --follow is passed on the command line

tig --follow Makefile

it appears that in this case, the graph option is silently ignored.

Expected behavior

Ideally, specifying --follow with the commit graph activated would work similar to git log --graph --follow, and display which branch the commit was on.

Any advice on how to work around this for now would be appreciated.
