[J3] spelling question

[Steven G. Kargl]

At the risk of derailing important topics such as the EOL of gfortran,
what is the correct spelling: arccosine vs "arc cosine", and should one
form be used consistently throughout the Fortran standard.  The former
appears in Table 16.1 and 16.9.4 for ACOS.  The latter is used everywhere
else in the F2023 standard for ACOSD and ACOSPI.  In fact, Table 16.1
in 24-007.pdf has the consescutive entries:

ACOS (X)      E Arccosine (inverse cosine) function.
ACOSD (X)     E Arc cosine function in degrees.


C17 (draft N2176.pdf) uses "arc cosine" consistently throughout.
C23 (draft N3096.pdf) uses "arc cosine".
ISO/IEC TS 18661-4:2015(e) uses "arc cosine" in the description of ACOSPI.
IEEE 754-2008 does not refer to functions by an English name (i.e., only the
function name acos).  DLMF simply refers to ACOS as the inverse cosine,
and uses neither arccosine nor "arc cosine".

Fortran standard spelunking finds that prior to the addition of
ACOSD and ACOSPI, the preferred spelling seems to be arccosine.
