+Description: remove BamBam_GetFastqPlusLineLength argument.
+ This change fixes the following build failure with gcc-15:
+ .
+        bambamc/BamBam_FormatAlignment.c: In function 'BamBam_GetFastqEntryLength':
+        bambamc/BamBam_FormatAlignment.c:47:17: error: too many arguments to function 'BamBam_GetFastqPlusLineLength'; expected 0, have 1
+           47 |                 BamBam_GetFastqPlusLineLength(qnamelen) +
+              |                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~
+        bambamc/BamBam_FormatAlignment.c:33:17: note: declared here
+           33 | static uint64_t BamBam_GetFastqPlusLineLength()
+              |                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ .
+ This is one of the rare cases where the right approach is to remove the
+ variable from the call, because the function is defined has being
+ hardwired to return 2 (1 + 1) and does not make use of any variable any
+ ways.
