Maxima 5.26.0 tagged in Git & posted to SF

Hi Robert,

we got some problems (using Ecl post-11.1.1).

First the build:

I think that's the usual thing, but just to mention (perhaps
something changed):

Running tests in rtest14: 
********************** Problem 144 ***************
Input:
closeto(AS_10_4_17(- 10), 1.e-15)


Result:

-------------------------------------------------- + airy_dai(- 10)
                        3

This differed from the expected result:
true


But then two new errors:

Running tests in rtest8:

------------------------------------

Running our own test, the print-function seems to have
a bug now:

In order to print out a string without line-breaks (whatever the length of the
string) we use

/* Print a string without line-breaks: */
print_nlb(s) := block([old_linel : linel],
  linel : slength(s) + 1,
  print(s),
  linel : old_linel)$

Now with 5.25.1. we get:
---
(%i2) print_nlb("XXX");

XXX 
Evaluation took 0.0000 seconds (0.0000 elapsed)
(%o2) 100
(%i3) print("XXX");

XXX 
Evaluation took 0.0010 seconds (0.0000 elapsed)
(%o3) "XXX"
---
As it should be. However 5.26.0 introduces an extra empty line:
---
(%i2) print_nlb("XXX");

XXX
  
Evaluation took 0.0010 seconds (0.0000 elapsed)
(%o2) 100
(%i3) print("XXX");

XXX 
Evaluation took 0.0000 seconds (0.0000 elapsed)
(%o3) "XXX"
---

That makes print_nlb unusable (by the way, is there a Maxima-function
to print a string on one line?).
