Jinja2 errors - line context failure

[hjoliver]

Report from user. A suite.rc file contains a Jinja2 include-file:

{% include 'splat-template.rc' %}

There's a clash between Jinja2 and bash syntax in line 94 of the included splat-template.rc:

​   if [[ ${#ALT_DIR} -lt ${#MAIN_DIR} ]]; then

but validation incorrectly points to line 94 of the main file:

$ cylc validate suite.rc
Jinja2Error:
  File "<unknown>", line 94, in template
TemplateSyntaxError: Missing end of comment tag
Context lines:
{% set NWP_SLS_STASHLIST="" %}
{% set NWP_SLS_VARLIST="" %}
{% set NWP_STASH2CF_FILE="stash2cf.xml" %}
{% set NWP_UM_EXTN="" %}        <-- Jinja2Error  [this is suite.rc line 94]
