A lot of spurious warnings after upgrading 1.7.0 -> 1.7.1

[jorisvandenbossche]

On the pandas doc build on travis, once it started using 1.7.1, there are a lot of warnings in the log output like (see eg https://travis-ci.org/pandas-dev/pandas/jobs/347059156, but there is a lot of other noise in the log output):

:1: (WARNING/2) Inline interpreted text or phrase reference start-string without end-string.
:1: (WARNING/2) Inline interpreted text or phrase reference start-string without end-string.
:1: (WARNING/2) Inline interpreted text or phrase reference start-string without end-string.

:1: (WARNING/2) Inline interpreted text or phrase reference start-string without end-string.
:1: (WARNING/2) Inline interpreted text or phrase reference start-string without end-string.

that were not there before (with 1.7.0).
It might be that those warnings are trying to warn for actual cases where there is a problem with this. But, the problem is they are not giving any context (in which file, which line is is raised?), so are somewhat useless.

Thank you for reporting. The warnings are emitted on creating autosummary tables. But it is not a problem of markups.
That's only bug of autosummary.

And thanks for fixing!
