Bug: Geiser (for implementation Guile) fails to find manuals unless info is previously invoked

[Calvin Heim]

Hi,

When I start a fresh Emacs instance and directly invoke run-geiser for the 
Scheme implementation Guile, 
and then invoke geiser-doc-look-up-manual on a symbol, I expect Geiser
to find the manual and look up the symbol. Instead, Autodoc responds, "Not 
documented as a symbol"

BUT if M-x info has previously been invoked in the Emacs instance before
Geiser has been invoked, then geiser-doc-look-up-manual succeeds in finding the 
manuals
and looks up the symbol.

I get this discrepancy with Emacs 26.3 and Geiser 0.11.2.
---------
While debugging, I noticed that geiser-guile--info-spec returns nil in the 
failure
scenario, and non-nil in the success scenario.

Backtrace from 
(debug-on-entry 'info-lookup-add-help) 
in the failure scenario:

 info-lookup-add-help(:topic symbol :mode geiser-guile-mode :ignore-case nil 
:regexp "[^()`',\" \011\n]+" :doc-spec nil)
  byte-code("\300\301\302\303\304\305\306\307\310\311\312 &\n\207"
