[elreq] Numbers need lines above and below (#121)

r12a has just created a new issue for https://github.com/w3c/elreq:

== Numbers need lines above and below ==
Digits have lines above and below. Modern practice tends to use discreet lines associated with each characters, however older texts used a single line across the whole set of adjacent digits. See examples in the <a href="https://w3c.github.io/elreq/#space_wordspace_substitution_rules">layout requirements document</a>. This difference is likely due to technology constraints. Presumably, a continuous line could be applied using OpenType functionality, but there may be a question about whether a control should allow to switch between one style and the other.

Try the <a href="http://w3c.github.io/typography/gap-analysis/tests/ethi/numeral-bars.html">test page</a>.

Initial results indicate that a single line is produced by Noto Sans Ethiopic and Noto Serif Ethiopic, but not by Kefa or Abyssinica SIL fonts.

There is a question as to whether this should be managed by font choice, or whether a switch should be available to users, eg. in CSS, that allows the desired approach to be applied.

In addition to the question just mentioned, a decision needs to be agreed regarding the impact of this feature for the user. For now, this is marked as basic.
