Two files collide on case-insensitive filesystems

[gaurav]

The following two files collide on case-insensitive filesystems (such as the default macOS filesystem):

• fhirlib/test/fhir/medreq-min-RDVch-expected.shexj
• fhirlib/test/fhir/medreq-min-rDVch-expected.shexj

You can see this if you clone this repository on macOS, when GitHub gives the following error:

warning: the following paths have collided (e.g. case-sensitive paths
on a case-insensitive filesystem) and only one from the same
colliding group is in the working tree:

  'fhirlib/test/fhir/medreq-min-RDVch-expected.shexj'
  'fhirlib/test/fhir/medreq-min-rDVch-expected.shexj'

Could we please rename one of these files to avoid this collision?

Ugh, I run into this problem every 10 years and think "surely case-insensitive filesystems have gone extinct by now".

The idea was e.g. R meant that Resource names were included in predicates, r meant they were not.
Names could be [Rɹ][Dp][Vʌ][Cɔ][Hɥ] ('cause [Rᴚ][D◖][Vᴧ][CↃ][HH] collides on H).
I guess the answer is to make the off flags be '_' or some such. That will affect readability some.
